! Introduction
|
|
|
|
A `tiddlywiki.files` JSON file in a sub-folder within [[a TiddlyWiki folder|TiddlyWikiFolders]] overrides the usual logic for recursively scanning the folder for tiddler files. Instead, the `tiddlywiki.files` file specifies instructions for loading tiddlers from specific files and folders.
|
|
|
|
The format of the file is an object with two optional properties:
|
|
|
|
* ''tiddlers'' - an array of objects describing external files with the ability to override or modify any of the fields read from the file
|
|
* ''directories'' - an array of objects describing external directories, a filter determining which files within those directories should be processed, and the ability to override or modify any of the fields read from the file
|
|
|
|
Note that significant enhancements to `tiddlywiki.files` processing were introduced in [[Release 5.1.14]].
|
|
|
|
!! Field overrides
|
|
|
|
Both the ''tiddlers'' and ''directories'' sections of `tiddlywiki.files` files include the ability to override or customise the values of fields with a `fields` object.
|
|
|
|
Each field can be specified as either a ''string'' or ''array'' value to be assigned directly to the field, or <<.from-version "5.1.14">> an ''object'' describing how to generate the value for the field. The object contains the following properties:
|
|
|
|
* ''source'' - (optional) a string specifying the source value for the field. If not specified, the existing value is used
|
|
** //filename// the filename of the file containing the tiddler
|
|
** //filename-uri-decoded// the filename of the file containing the tiddler, with [[URI decoding|https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/decodeURIComponent]] applied
|
|
** //basename// the filename of the file containing the tiddler without any extension
|
|
** //basename-uri-decoded// the filename of the file containing the tiddler without any extension, with [[URI decoding|https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/decodeURIComponent]] applied
|
|
** //extname// the extension of the filename of the file containing the tiddler
|
|
** //created// the creation date/time of the file containing the tiddler
|
|
** //modified// the modification date/time of the file containing the tiddler
|
|
* ''prefix'' - (optional) a string to be prepended to the value of the field
|
|
* ''suffix'' - (optional) a string to be appended to the value of the field
|
|
|
|
! Tiddlers section
|
|
|
|
The file specifications in the `tiddlers` array support the following properties:
|
|
|
|
* ''file'': (required) the absolute or relative path to the file containing the tiddler data (relative paths are interpreted relative to the path of the `tiddlywiki.files` file)
|
|
* ''isTiddlerFile'': (optional) if `true`, the file will be treated as a [[tiddler file|TiddlerFiles]] and deserialised to extract the tiddlers. Otherwise, the raw content of the file is assigned to the `text` field without any parsing
|
|
* ''fields'': (optional) an object containing values that override or customise the fields provided in the tiddler file (see above)
|
|
* ''prefix'' & ''suffix'': (optional) strings to be prefixed and suffixed to the tiddler `text` field
|
|
*> Note that providing a ''prefix'' here is equivalent to setting the `text` field of the ''fields'' object to `{"prefix":"<prefixvalue>"}`.
|
|
|
|
! Directories section
|
|
|
|
Directory specifications in the `directories` array may take the following forms:
|
|
|
|
* a ''string'' literal, specifying the absolute or relative path to the directory containing the tiddler files (relative paths are interpreted relative to the path of the `tiddlywiki.files` file). The directory is recursively searched for tiddler files
|
|
* <<.from-version "5.1.14">> an ''object'' with the following properties:
|
|
** ''path'' - (required) the absolute or relative path to the directory containing the tiddler files (relative paths are interpreted relative to the path of the `tiddlywiki.files` file). Note that the directory is not recursively searched; sub-directories are ignored
|
|
** ''filesRegExp'' - (optional) a [[regular expression|https://developer.mozilla.org/en/docs/Web/JavaScript/Guide/Regular_Expressions]] that matches the filenames of the files that should be processed within the directory
|
|
** ''isTiddlerFile'' - (required) if `true`, the file will be treated as a [[tiddler file|TiddlerFiles]] and deserialised to extract the tiddlers. Otherwise, the raw content of the file is assigned to the `text` field without any parsing
|
|
** ''isEditableFile'' - (optional) if `true`, changes to the tiddler be saved back to the original file. The tiddler will be saved back to the original filepath as long as it does not generate a result from the $:/config/FileSystemPath filters, which will override the final filepath generated if a result is returned from a filter. <<.from-version "5.1.23">>
|
|
** ''fields'' - (required) an object containing values that override or customise the fields provided in the tiddler file (see above)
|
|
|
|
Fields can be overridden for particular files by creating a file with the same name plus the suffix `.meta` -- see TiddlerFiles.
|
|
|
|
! Examples
|
|
|
|
These example `tiddlywiki.files` must be placed in their own sub-directory of the [[wiki folder|TiddlyWikiFolders]].
|
|
|
|
There are also several examples of `tiddlywiki.files` files in the main [[TiddlyWiki 5 GitHub repository|https://github.com/Jermolene/TiddlyWiki5]].
|
|
|
|
!! Importing a folder of PDFs
|
|
|
|
This example retrieves all the files with the extension `.pdf` from a folder specified by a relative path. This path starts with "../../../" indicating 3 directory levels above the folder holdng this confog fole. Each tiddler is set up for LazyLoading with the following fields:
|
|
|
|
* ''title'' - set to the URI decoded base filename of the PDF file. [[URI decoding|https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/decodeURIComponent]] allows characters like "/" to be included in titles by URI encoding them as "%2F"
|
|
* ''created'' - set to the creation date/time of the PDF file
|
|
* ''modified'' - set to the modification date/time of the PDF file
|
|
* ''type'' - set to `application/pdf`
|
|
* ''tags'' - set to `$:/tags/AttachedFile`
|
|
* ''text'' - set to an empty string
|
|
* ''_canonical_uri'' - set to the string "pdfs/" concatenated with the filename
|
|
|
|
```

|
|
!! Importing a folder of text files
|
|
|
|
This example retrieves all the files with the extension `.txt` from a folder specified by a relative path. This folder is within the wiki's base directory, and the current config file is in a directory within the wiki's "tiddlers/" directory. So, in this case the path starts with "../../" to traverse upwards two directory levels, and then down into the "externalnotes/" directory. Each tiddler is set up with the following fields:
|
|
|
|
* ''title'' - set to the URI decoded base filename of the text file. [[URI decoding|https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/decodeURIComponent]] allows characters like "/" to be included in titles by URI encoding them as "%2F"
|
|
* ''created'' - set to the creation date/time of the text file
|
|
* ''modified'' - set to the modification date/time of the text file
|
|
* ''type'' - set to `text/plain`
|
|
* ''tags'' - set to `[[note]] [[externalnote]] [[.txt]]` (using array notation)
|
|
* ''text'' - not set, thus the content of the file is loaded as the text field
|
|
|
|
```
|
|
{
|
|
"directories": [
|
|
{
|
|
"path": "../../externalnotes",
|
|
"filesRegExp": ".+\\.txt",
|
|
"isTiddlerFile": false,
|
|
"isEditableFile": true,
|
|
"fields": {
|
|
"title": {"source": "basename-uri-decoded"},
|
|
"created": {"source": "created"},
|
|
"modified": {"source": "modified"},
|
|
"type": "text/plain",
|
|
"tags": ["note", "externalnote", ".txt"]
|
|
}
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
This will load all text files in the `../../externalnotes/` directory into the wiki as individual tiddlers. These can be a collection of snippets in various markup-languages. Then, the `type` field of each of these tiddlers can be changed to match their languages For example, "text/vnd.tiddlywiki" for wikitext, or "text/markdown" for markdown files. Then, using $:/config/FileSystemPaths and $:/config/FileSystemExtentions tiddlers with the following lines we can cause any changes to these tiddlers to be saved back to the directory they started from, and also as "*.txt" files with accompanying "*.txt.meta" files. These meta files will be generated as required, and will then over-ride any fields generated from the config `tiddlywiki.files` file (such as the tiddler's `type` field) when the server is restarted.
|
|
|
|
From the examples in [[Customising Tiddler File Naming]] we see that the final `[!tag[externalnote]addprefix[wiki/]]` filter in the $:/config/FileSystemPaths tiddler excludes all tiddlers tagged with `externalnotes` (that have not matched an earlier filter). These tiddlers have their filepath retrieved from the $:/config/OriginalTiddlerPaths generated upon boot startup.
|
|
|
|
Then, the `[tag[.txt]then[.txt]]` filter in the $:/config/FileSystemExtensions tiddler forces all these tiddlers to be saved back to disk as *.txt and accompanying *.txt.meta files (overriding the normal tiddler-type to file-type mapping). In this case, allowing the snippets of Tiddlywiki wikitext or markdown-text to be saved back to "text" *.txt files. |
